AI Technical Summary

Benefits of technology

Enables simple one-touch attachment and detachment of the cap without the need for threads or engaging holes, reducing mold complexity and costs, while ensuring reliable sealing and preventing accidental dislodgment.

Problems solved by technology

This arrangement, however, does not take into consideration the detachment (removal) of the engaged cap from the opening.
Therefore, this arrangement cannot be applied to cap mounting arrangements for opening and closing the opening of a container.

embodiment 1

Variant of Embodiment 1

[0058]FIG. 6 shows a variant of the first embodiment of the invention.

[0059]In this variant, a shoulder 31 is provided in an axially intermediate portion of the cylindrical part 9 of the cylinder head cover 3, and the cylindrical part 9 is divided into a small-diameter part 33 forming an upper half and a large-diameter part 35 forming a lower half by the shoulder 31. Further, the cylindrical part 17 of the cap 1 is set at a length that locates very close to the shoulder 31 outside of the small-diameter part 33 of the cylindrical part 9 when it is engaged with the cylindrical part 9. Furthermore, the cylindrical part 17 is formed at its inner periphery with a sealing groove 17a into which an O-ring 21 is seated. In short, in this variant, the cylindrical part 17 of the cap 1 is fitted on the small-diameter part 33 of the cylindrical part 9 of the cylinder head cover 3. Since the structures other than the above points are the same as in the first embodiment, the...

embodiment 2

Variant of Embodiment 2

[0084]The second embodiment of the present invention may have the following configurations.

[0085]Though the container is a cylinder head cover 101 in the second embodiment, the present invention is applicable to any container having a cylindrical part with an opening.

[0086]In the second embodiment, each receiving recess 117 is provided with a projection climbing surface 117b gradually decreasing its depth from the bottom 117a in the circumferential direction and each push-out projection 127 has a rounded top surface. Instead of this, the projection climbing surface 117b may be formed perpendicular to the bottom 117a or the push-out projection 127 may be a rectangular column. On the contrary, the top surface of the push-out projection 127 closer to the projection climbing surface 117b may be formed into an inclined flat surface (or curved surface) while the projection climbing surface 117b may be formed perpendicular to the bottom 117a. In short, it is essentia...

Abstract

A cap has a pair of L-shaped, flexible engaging arms that extend, from the end of a cap body opposite to the direction of fitting, in the direction of fitting with a distance away from the cap body. The distal ends of the engaging arms are connected by a pair of flexible connecting bridges to surround the outer periphery of the cap body with a distance away therefrom. The cap body is fitted into a cylindrical part of a cylinder head cover and engaging projections of the pair of engaging arms are engaged with an engaging recess in the outer periphery of the cylindrical part. The engaging arms are flexed to get away from the outer periphery of the cylindrical part by pushing circumferentially middle parts of the connecting bridges to come close to each other, so that the engaging projections are disengaged from the engaging recess.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is a Divisional of application Ser. No. 11 / 058,358 filed Feb. 16, 2005.[0002]This application claims priority under 35 USC 119 to Japanese Patent Application No. 2004-271888, filed on Sep. 17, 2004, the entire contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0003](a) Field of the Invention[0004]This invention relates to a cap mounting arrangement in which a cap with a sealing member is detachably attached to a container to hermetically closes an opening of the container.[0005](b) Description of Related Art[0006]Cap mounting arrangements of this type have conventionally been used, for example, for oil caps for engine oil filling provided on cylinder head covers in automobile engines. These oil caps are generally of a screw type which is fitted with an O-ring as a sealing member and closes an opening of a cylinder head cover by screwing internal threads formed on the opening of the cylinder ...
